Help required for photographing horse racing

Hello to one and all,
I have not long purchased a Panasonic g3 with a twin lens kit, can you help as to what camera settings might give me the best chance to capture action shots. I realise the continuous shoot mode in full resolution of 4 frames per sec is not the greatest, but we all have to start somewhere! Right?

Are you, by any chance, attending "Photographer's Day at the Santa Anita, California, track. I mentioned this because I am attending and it will only be my second time at any track and the first time shooting the action...

That has helped enormously, thank you very much, the article looks a massive help.

I live in the UK so Santa Anita is a no,but I hope you fall in love with the sport I adore so much. Having the odd own taken picture of various racetrack excursions dotted around the house has been fun to do.
